Big Sur and AppleThunderboltNHI.kext

[tough.hard.together]

Yes this time from recovery mode

 

[notgoingoutside]

Damn...!! Hard luck..even after doing it all.. thunderbolt drivers are still being loaded... and shut down is still happening ????


Ok Guys So Here’s the FIX with BIG SUR


I did few modifications with whatever was available on internet to solve this problem


Step 6 & 7 are few modifications which I did.


Here it goes





Reboot in recovery mode (CMD+R)

1. Utilities -> Terminal
2. csrutil disable
3. csrutil authenticated-root disable
4. mount - uw /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)
5. cd /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/Extensions
6. rm -rf AppleThunderboltNHI.kext
7. rm -rf /System/Library/Caches/*
8. Kmutil install -u --force --volume-root /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/Extensions
9. bless -folder /Volumes/Macos(Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/CoreServices —bootefi --create-snapshot

FORGET THE PROBLEM :-D


You’ll need to perform these steps every time you update Big sur with their security updates n all.


No need to enable SIP


Have a good life

This is what has worked for me as well. Do you know the impact of not enabling SIP?

Do you know the impact of not enabling SIP?

SIP is a security feature that prevents modification of system files. It's one level of protection against malware.

I did what sodhi07 recommended, and it didn't work. My mac still shut down after a few minutes.

So I went back into recovery mode and renamed all the AppleThunderbolt and IOThunderbolt files to ".bak" files.

STILL DOESN'T WORK.

Any thoughts?

I recommend you, please read my method again. Carefully read it. I am using big sur on my mbp 2014... and haven't experienced shut down after that. My method works 100% ... tried and tested two times

Hello there, i am new to the community and i have this problem too, i dont have much knowledge about Terminal stuff but maybe you could help me out fixing the problem.

1. Reboot in rescue mode (reboot while "Cmd + R")
2. csrutil disable
3. csrutil authenticated-root disable

Theese Steps went well so far, i restarted as needed and loged into my Admin Account. I opened the Terminal and tried following.

Don't restart. Go on to step 4 even though csrutil tells you to restart.

I carefully followed the steps, and even after rebooting, I confirmed by going to Terminal and listing the contents of /System/Library/Extensions that the AppleThunderboltNHI.kext (and the others I deleted) are NOT THERE.

I have a mid-2014 MacBook pro, and this fix has always worked for me before. I don't know why it's not working with Big Sur?!

Also, as others have noted, as long as I have my external monitor hooked up, my MacBook doesn't crash.

 

[tough.hard.together]

yea But still i got told to mount my harddrive "Daten" but there is no Daten>System/Library/Extensions/AppleThunderboltNHI.kext its under Apple SSD SM0512F>System/Library/Extensions/AppleThunderboltNHI.kext to find but i cant mount the Apple SSD SM0512F

like u see on the screenshot and even if i dont reboot i get the error on trying to mount it

it still tells me i only have read persmissions. Something needs to be wrong, maybe u can find a misstake on the screenshot :/

I can find the file under Daten/Volumes/Apple SSD SM0512F/System/Library/Extensions/AppleThunderboltNHI.kext but then i am back to daten and i get the Error that i got Read only permissions.

Hi there,

running MBP mid 2014 and habing the same issues. Lived with that -delete nhi routine- for years and now went for big sur. Big mistake ?

I followed each and every step of your guide. I even double checked that all those kexts are deleted from my volume.
When I boot into normal mode after that and check in /System/Library/Extensions I can confirm: no AppleThunderboltNHI.

But kextstats still show that it‘s loaded and the random shutdowns still occur.

As if those kexts were loaded from some other place.

Is there any way to confirm the kmutil or bless did it right? Like checking the correct snapshot is chosen at boot?

MiO

So I have followed this excellent guide, but even with SIP and Authenticated root disabled, I can't delete the kext. I can't do it in recovery or with sudo or in a root enabled account. Clearly I'm missing something...

Every time it continues to tell me that it is that the package contents instead the .kext are on a read-only file system. Even though if I look at them in finder (root account) it says read/write ?

Hi! I followed every step that you recommend, yet on the final step (bless...) I get this message for some reason:

“Couldn’t root snapshot on volume /Volumes/MacSSD: Read-only file system”

What might be causing this?

 

[Rstk]

This is a such an odd issue. Anyone knows what's causing it ? It's hardware failure or a bug ?

 

[pixhub]

Reboot in recovery mode (CMD+R)

1. Utilities -> Terminal
2. csrutil disable
3. csrutil authenticated-root disable
4. mount - uw /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)
5. cd /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/Extensions
6. rm -rf AppleThunderboltNHI.kext
7. rm -rf /System/Library/Caches/*
8. Kmutil install -u --force --volume-root /Volumes/Macos (Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/Extensions
9. bless -folder /Volumes/Macos(Enter WHATEVER YOUR MACOS DRIVE NAME IS, my macOS drive name is Macos)/System/Library/CoreServices —bootefi --create-snapshot

do this, it works after restart from recovery mode for 1 times. A restart from the working systems runs in a reboot loop:

"Your computer restarted becouse of a problem. ..."

 

[amanjeetarora]

Hi I tried the method mentioned by sodhi07 for MacBook No crash steps for the thunderbolt drive and its not working for me on MacBook pro late 2013 can you please help me with your email let me reach out to you.
my email is amanjeetarora@gmail.com

 

[asangam]

This is exactly my situation!!!

I think it's the same for me too.

I did everything right I guess haha.
I was able to delete the NHI file and everything. But still my MBP is still crashing. I checked in the Thunderbolt section under Software Report it still shows the Thunderbolt driver information. I cleared the cache and everything @sodhi07 said but that still didn't fix for me.

Because I don't want to go over reinstalling the Catalina and liked how Big Sur was I did the python script way. There's a 3/4 line python script if that is executed that will stop the crash and shutdown problem.

I'll post that script after my work.

Good day everyone.

Edit: Added the photo from my phone. Not a good one but is readable.

 

[Diwad]

Anyone of you tried this on m1 device? When I try to rebuild kezt cache it gives me error: "Not rebuilding KC for arch: 'aem64e'"

 

[wills11]

Hey, all!

I'm getting random shutdowns/restarts—but without any error message on restart—and am wondering how I'd determine if this is what's causing them? Is there something to check for in Console?

Thanks in advance!

 

[KaiThePirate]

Are we going to have to do the lather, rinse, repeat every time? Now that 11.1 is out has anyone experienced the shutdown?

 

[Bushsong]

Are we going to have to do the lather, rinse, repeat every time? Now that 11.1 is out has anyone experienced the shutdown?

Yes, I finally got 11.1 installed after incredible problems. Took 3 downloads of the software from the Apple server. The download I did and the upgrade, (which happened inadvertently by the way), bricked the Mac. Consistently failed and took me 24 hours to get the machine back. Quite frankly I don't even know what I did except kept downloading and reinstalling Big Sur until it worked. The machine is working OK, but that old problem is still there with shutting down. Apple really needs to come up with a fix for this, or perhaps they are waiting for next year when they tell us our machines are redundant. If the new M1s work OK then I'll be upgrading anyway.

Be interested to know if anyone has solved the issue with Big Sur. The fix detailed above didn't work for me.

 

[KaiThePirate]

Well, 11.1 got installed over night and even after doing the fix, it's still shutting down. Guess it's back to Catalina for me.

 

[tough.hard.together]

Hello, thanks alot for your help. I could solve it with this Site... too 100%

Random Shutdown in Big Sur (Thunde… | Apple Developer Forums

developer.apple.com

Here i have some tipps and minor issues i had with the solution. Its actually the same like on this sits, but maybe this can help you. I tried to explain every step i took. I hope it helps and awares some stupid issues for you.

1. Start in Recovery Mode (Boot your system and hold down CMD + R)

2. Choose your Language

3. Start the Terminal Menubar > Developer Tools > Terminal

4. csrutil disable

csrutil disable​

​

5. authenticated root disable

csrutil authenticated-root disable​

​

6. Restart Recovery Mode (Apple Icon > Restart and hold down CMD + R)

7. Start the Terminal again

8. Mount the Harddrive

-- Note --
Everywhere where you find "Harddrive\Name" you should replace it with the name of your Harddrive or it won't work. The Name of your Harddrive, can be found in the "Diskutility Tool". If your Harddrive Name has a space inbetween, replace the space with an --> \ <-- Backslash.

8.1 Info​

Read this please, even if this is just an example, but i did here some misstakes, i better tell you if you dont have any ideas of terminal usage like i had. After you read it you can go on with 8.2. ​

​

Here i had the biggest problems, my Hard Drive is called "Apple SSD SM0512F" and is splitted into 2 Partitions "Daten" and "WorkBench", so what i had to Mount was the Apple SSD SM0512F and Daten, for me it didnt worked with only mounting the Harddrive.​

​

So istarted typing ​

mount -uw /V ​

​

now i pressed Tab so it completed it to ​

mount -uw /Volumes/​

​

so i typed on and pressed Tab again (tab Autocompletes the first possibility with the letters u entered befor) if you dont want to press Tab type it by Hand", but you can refuse some misstakes with it. Humans always do mistakes.​

mount -uw /Volumes/A​

​

here came my next problem... it completed it to​

mount -uw /Volumes/Apple\SSD\SM0512F/​

​

I needed to remove the last "/" or it gives an Error for unknown File System​

mount -uw /Volumes/Apple\SSD\SM0512F​

​

Correct ​

mount -uw /Volumes/Apple\SSD\SM0512F​

​

Incorrect ​

mount -uw /Volumes/Apple\SSD\SM0512F/​

​

-- Note --​

Your Harddrive can have a different Name i find out the right name under Diskutility tool.​

Use the name you had Choosen earlier...​

​

if its called "MacOS"​

"mount -uw /Volumes/MacOS"​

if its called MacSSD​

"mount -uw /Volumes/MacSSD"​

Just as an example to understand it​

​

After that i mounted my Partition Daten (better do it it could cause problems if you dont do it) when you got partitions. Maybe its just for me, because my partitions are existing for a very long time: since SnowLeopard) and again take care for the last Slash --> / <--)​

8.2 Mount the Harddrive​

mount -uw /Volumes/Harddrive\Name​

-- Note --​

For me it was ​

mount -uw /Volumes/Apple\SSD\SM0512F​

​

8.3 Mount the Partition​

mount -uw /Volumes/Harddrive\Name/Partition\Name​

-- Note --​

For me it was ​

mount -uw /Volumes/Apple\SSD\SM0512F/Daten​

9. Rename or Remove the "AppleThunderboltNHI.kext"

mv /Volumes/System/Library/Extensions/AppleThunderboltNHI.kext /Volumes/System/Library/Extensions/AppleThunderboltNHI.kext.BAK​

​

10. Check it

Move to the Extensions​

cd /Volumes/Harddrive\Name/System/Library/Extensions/ ​

List all Files​

ls​

If you find the "AppleThunderboltNHI.kext.BAK" you did everything right, but be careful it realy has to be called "AppleThunderboltNHI.kext.BAK"​

​

11. REBUILD the extensions cache

New in BigSur ​

kmutil install -u --force --volume-root /Volumes/Harddrive\Name​

​

-- Note --​

For me it was ​

kmutil install -u --force --volume-root /Volumes/Apple\SSD\SM0512F​

​

12. create another system snapshot

bless --folder /Volumes/Harddrive\Name/System/Library/CoreServices --bootefi --create-snapshot ​

​

-- Note --​

For me it was ​

bless --folder /Volumes/Apple\SSD\SM0512F/System/Library/CoreServices --bootefi --create-snapshot​

​

13. csrutil enable
14. csrutil authenticated-root enable
15. Restart in Normal Mode

Info​

For me it caused a Problem. I came into a Crash routine with blackscreen, but alot of people had this problem. ​

The Error massage after the Restart followed with a blackscreen and said "press a Key to restart!". ​

​

If you have the same issue do following​

​

1. Restart in recovery mode​

2. Start the "diskutility tool"​

3. Click on your Harddrive and choose "First Aid" and "run it"​

5. Click on your Snapshot and choose "First Aid" and "run it"​

6. Exit the "diskutility tool"​

7. Run "Terminal" again​

8. csrutil disable​

9. Restart in recovery mode​

10. Restart in Normal mode​

​

16. Enjoy and have Fun without any stupid crashes

Info​

The security mode of BigSur is deactivated, but you still have the security mode of Catalina active. So this is the only small minus at this solution.​
